Thompson 5 eedless g rape bunches f rom a farm In Kaliobeya governorate treated separately by GAJ(40 ppm), by cppu ( 3 ppm and 5 ppm ) and by a combination of GAl and both doses of cppu, were culled at optimum maturity, and wrapped in polyethylene vented bags and kept in cartons. Half of the bags were provided with S02 generating sachets. The bags were divided Into storage in ambient conditions (3 days) and In cold store ( 6 weeks at OoC ). By end of storage period, grape quality was evaluated, and exemption of decay was estimated. Joint application of cppu and GA3 Increased "markedly cluster and beny weight compared to control, and So2 generators were effective In limiting decay Infection. Application of cppu alone or combined with GA3 delayed maturity, and decreased total soluble solids after cold storage or ambient slay periods, as compared 10 control. Acidity was also higher In the above mentioned applications.
